What Is Indexed Universal Life (IUL)?

Indexed Universal Life (IUL) is a type of permanent life insurance that combines a death benefit with cash value growth linked to a stock market index, featuring a floor that protects against losses.

How an IUL Works

An IUL policy provides a permanent death benefit plus a cash value component. The cash value earns interest based on the performance of a market index (usually the S&P 500), subject to a floor and a cap.

The floor (typically 0%) means your cash value never decreases due to market losses. The cap (typically 9-14%) limits the maximum credit in any period. You get market upside with downside protection.

Key Features

IULs offer several features that distinguish them from other life insurance types:

  • Flexible premiums — pay more in good years, less in lean years
  • Tax-deferred cash value growth
  • Tax-free policy loans for supplemental retirement income
  • Permanent coverage — no expiration date
  • Living benefit riders for terminal or critical illness

Who Is an IUL Best For?

IULs work best for people with long time horizons and goals beyond basic income replacement: business owners building tax-advantaged reserves, high earners supplementing retirement savings, or parents building a legacy asset. They are not ideal for short-term needs or purely budget-conscious coverage.

Frequently Asked Questions

What is the difference between IUL and whole life?
IUL has flexible premiums and market-linked growth with a cap and floor. Whole life has fixed premiums and guaranteed (but lower) cash value growth. IUL offers higher growth potential with more complexity.
Can you lose money in an IUL?
Your cash value cannot decrease due to market performance because of the 0% floor. However, policy fees and cost of insurance charges are deducted regardless of market performance.
How are IUL policy loans taxed?
Policy loans from an IUL are generally not considered taxable income. However, if the policy lapses with an outstanding loan, the loan balance may become taxable.
What is the average return on an IUL?
Historical average credited rates typically range from 5-8% annually, though this varies by carrier, index strategy, and market conditions. The floor and cap structure means returns are more moderate but more stable than direct market investment.
